Anybody ever use this as a final finish on a gun stock? I was told that it is far superior to Tru Oil. So far I've used it on the forend of my 1897 Winchester, and two coats on the stock, and it seems to be doing a fair job in filling in the pores of the wood. I'm wondering on how many coats it is going to take to get a final finish (I'm hand rubbing it in btw)? How about the durability of the finish?
